Abstract

A preset tuner includes a memory (14) having storage positions for storing a plurality of frequency data for a number of preset channels. In the tuner, one of a plurality of preset keys (17) is operated. The number of times of operating that key after operating another preset key is detected in the case where the operation on the one preset key is finished within a predetermined time period, and one storage position corresponding to the detected number of times of operating the one preset key is designated among a plurality of storage positions in the memory corresponding to a channel designated by operating the one preset key. If the operation on the one preset key is not finished within the predetermined time period, frequency data supplied to a front end (2) is written into the designated storage position, while if the operation on the one preset key is finished within the predetermined time period, frequency data is read from the designated storage position and supplied to the front end, thereby performing the preset channel selection.
